I started taking Spanish lessons in the fall through Pimsleur. It's an approach that relies heavily on listening, repeating, and then responding to conversational phrases. Today I completed my 51st lesson, which means I'm 21 lessons into level 2. (Image of the Spanish Steps in Rome, from Wikimedia Commons.)
As soon as I started the first lesson, I decided that I would take lessons while pacing my room. That way, I not only get in a few steps towards my fitness goal, but I am learning to walk and talk Spanish at the same time. Foreign languages are not my forte, so it is a big deal to be able to walk and talk. That combined skill will help me should I ever get to travel again to a Spanish speaking country.
